[WITH<ENCRYPTION JI[ RECOMPILE ]I[EXECUTEASClause ]>] [FORREPLICATION]ASBEGIN-- SQL语句return@参数2;-- 可以不返回END procedure_name:新存储过程的名称,并且在架构中必须唯一。可在procedure_name前面使用一个数字符号(#)(#procedure_name)来创建局部临时过程,使用两个数字符号(##procedure_name)来创建全局...
This article describes how to recompile a stored procedure in SQL Server by using Transact-SQL. There are three ways to do this: WITH RECOMPILE option in the procedure definition or when the procedure is called, the RECOMPILE query hint on individual statements, or by ...
Performance:After the first execution of the stored procedure, the query optimizer creates an execution plan and this plan is stored in the query plan cache. So that, all next executions of the same SQL Server stored procedure will use this cached stored procedure. This methodology aims to avoi...
同时,存储过程可以接收和输出参数、返回执行存储过程的状态值,也可以嵌套调用 CREATE PROCEDURE [拥有者.]存储过程名[;程序编号] [(参数#1,…参数#1024)] [WITH {RECOMPILE| ENCRYPTION |RECOMPILE, ENCRYPTION} ] [FOR REPLICATION] AS 程序行 GO 例如: CREATE procedure sp_No1 @aint, @bchar(10)asselect...
SQL Server's statement-level recompilation behavior is mimicked. But in addition to using the procedure's current parameter values, the RECOMPILE query hint also uses the values of any local variables inside the stored procedure when you compile the statement. For more information, seeQuery Hint...
Our organization has a stored procedure, that seems to always be recompiled and reparsed nearly every execution, adding upwards of 14 seconds to overall execution time. The procedure is frequently but irregularly run, so it becomes common for users to…
Example: Simple Stored Procedure Copy CREATE PROCEDURE uspGetEmployeeList AS BEGIN SELECT EmpID ,FirstName ,LastName FROM dbo.Employee ENDExecute the above T-SQL script in the query editor to compile and create it in the database, as shown below.The...
StoredProcedure+ Name: string+ Parameters: list+ Query: string+Compile() : void 在类图中,StoredProcedure表示存储过程的类,包含存储过程的名称、参数、查询语句以及编译方法。 结论 重新编译存储过程是确保其性能和准确性的重要步骤。通过使用sp_recompile存储过程,我们可以简单快速地重新编译存储过程,以适应数据变...
您是否一直在更新数据库的统计信息?这听起来像原来的 SP 使用了一个过时的查询计划。 sp_recompile 可能会有所帮助,而不是删除/重新创建它。 相关讨论 如果更新统计后行为返回,肯定是参数嗅探 过时的统计数据会更频繁地导致问题,没有更新 = 不正确的计划,也没有理由从缓存中弹出。删除/创建意味着新计划,所以它...
sp_recompile --使存储过程和触发器在下次运行时重新编译。 sp_refresh_log_shipping_monitor --使用指定日志传送代理的给定主服务器或辅助服务器中的最新信息来刷新远程监视器表。 sp_refreshsqlmodule --更新当前数据库中指定的非绑定到架构的一些对象。 sp_refreshsubscriptions --对于所有现有的订阅服务器,将对其...
